In addition to traditional usability issues, evaluation studies for personalized Web sites and applications must consider concerns specific to these systems. In the general case, usability studies for computer-based applications attempt to determine whether the software, in actual use, meets users’ needs, whether users can accomplish their goals in using the software, whether users can understand and use the application (whether they comprehend what they can do, and how), the rate, frequency, and severity of user errors, the rate of, and time duration for, task completion, and so on. But in the case of user-centered evaluations of personalized Web sites, there are additional questions and issues that must be addressed. In this paper, we present some of these, based on our experience in us-ability studies of a personalized eCommerce site.

Abstract The integration of user-centered design (UCD) activities into agile information systems development has become more popular recently. Despite the fact that there are many ways the merging of UCD activities into agile development can be carried out, it has been widely recognized that coordinating design activities with development activities is one of the most common problems, especially in distributed environments where designers, developers and users are spread over several sites. The main approach to coordinate UCD activities with distributed agile development is the use of informal methods (e.g. communication through using video conference tools). In addition to the temporal, geographical and socio-cultural barriers associated with this type of methods, a major limitation is a lack of awareness of how UCD activities and development activities affect each other. Furthermore, some agile project management tools are integrated with design platforms but fail to provide the necessary coordination that helps team members understand how the design and development activities affect their daily work. This research aims to support the effective management of integrating UCD activities into distributed agile development by (i) identifying the key activity dependencies between UX design teams and development teams during distributed UCD/agile development and (ii) designing a computer-based system to provide coordination support through managing these activity dependencies. In order to achieve these objectives, two case studies are carried out. Our findings revealed 10 main dependencies between UCD design teams and development teams as shown by six types of activity. In addition, the participatory design approach shows that developing a computer-based system to manage seven of these selected dependencies is achievable.

This study was aimed to investigate the determinants of actual use of computer based transaction processing system among employees in minimarkets in Padang, Indonesia. In addition to Perceived ease of use and perceived usefulness which are the basic models of Technology Acceptance Model (TAM), Subjective norm was conceptualized as an external variable that affecting Technology Acceptance among users of transaction processing system. In total, 246 employees participated in this study. The results show that the perceived ease of use positively affects Perceived Usefulness and Attitude. Furthermore, perceived usefulness and subjective norm have positively affected on Attitude. Likewise Attitude has positively affected on Actual Use. This study reveals that employees tend to comply the peers’ opinion on using transaction processing system. For future research is expected to expand the TAM model by adding external variables and individual characteristics as a moderator variable

Educational evaluators in general have traditionally recognized the need to incorporate data from potential users in designing evaluation studies. In the field of courseware evaluation, however, there has been a great deal of emphasis placed on expert judgment as a source of data for evaluating computer-based educational materials. Although courseware reviews are extremely useful, they are not substitutes for field tests;each provides a different type of information that evaluators may use in order to determine the quality of an instructional product.This paper reports on the evaluation of a courseware designed to assist the writing of the lower-case alphabet. The main objective of the article is to demonstrate an evaluation design which provided adequate answers to our evaluation questions, allowed us to perform multiple comparisons to support our conclusions, and was also practical enough to be used in a normal classroom situation without disturbing everyday activities. Three criteria for selecting a design are presented followed by a description of the courseware evaluation.

In this article the authors describe how they incorporate eye tracking in a human-computer interaction (HCI) course that forms part of a postgraduate Informatics degree. The focus is on an eye tracking assignment that involves student groups performing usability evaluation studies for real world clients. Over the past three years the authors have observed how this experience positively affected students' attitude towards usability and user experience (UX) evaluation. They therefore believe that eye tracking is a powerful tool to convince students of the importance of user centered design. To investigate the soundness of their informal observations, the authors conducted a survey amongst 2016 HCI students and analysed student course evaluation results from 2014 to 2016. The findings confirm that students regard the eye tracking assignment as a mind altering experience and that it is potentially an effective tool for convincing future IT professionals of the importance of usability, UX and user centered design.

Articulating thought in computer-based media is a powerful means for humans to develop their understanding of phenomena. We have created DynaLearn, an Intelligent Learning Environment that allows learners to acquire conceptual knowledge by constructing and simulating qualitative models of how systems behave. DynaLearn uses diagrammatic representations for learners to express their ideas. The environment is equipped with semantic technology components capable of generating knowledge-based feedback, and virtual characters enhancing the interaction with learners. Teachers have created course material, and successful evaluation studies have been performed. This article presents an overview of the DynaLearn system.

In this paper, we introduce a notation that highlights necessary elements in a practice-centered design process and which can be used to describe a set of common errors committed by design organizations leading to computer-based systems that create new burdens for practitioners. These common design errors result from an organizational tendency to underinvest in modeling error and expertise and using prototypes to discover requirements. The former underinvestment can lead to designs based on uninformed, underspecified, and unexamined models of the relationship between technology and human performance. The latter can lead to commitment to a design concept before fully exploring the range of possible solutions. We suggest ways to avoid these problems by setting forth a balanced organizational investment strategy that would enhance the possibilities for the development of useful systems.

1 Thirteen UK pharmaceutical companies have provided comprehensive toxicological data from repeated-dose animal safety evaluation studies of 74 pharmaceutical compounds. 2 These data comprise a unique toxicology database and this paper describes its establishment including the problems encountered, its current size with over 35 000 data fields, its content and potential value for retrospective analyses. 3 Increasing reliance on animal studies for predicting the safety of medicines in man necessitates a reappraisal of conventional animal testing procedures and better use of the considerable volume of data in the archives of regulatory authorities and pharmaceutical companies. This reappraisal may be achieved by the use of computer-based toxicology databanks.
